Duke Zhou dreamed that he was walking by the river.

I dreamed of walking in the river, but the water was not too deep: my family would have good luck. Father's promotion, mother's illness, or brother's admission are all expected. You can also live in peace for a while. Unmarried men dream of walking in the river, but the water is not too deep, which is the main reason of wealth: bad. The students dream of walking in the river, but the water is not too deep, which shows that they have done well in the exam.
